My point, which you seem determined to miss, is that by engaging in ANY discussion of what new gun laws might or might not help curb "gun violence" you tacitly acknowledgement that "gun violence" is the problem. If "gun violence" is the problem, then "gun" solutions might be appropriate.

But ... the problem is NOT 'gun violence," so IMHO you are missing the opportunity to redirect the debate toward where it needs to go by engaging in discussions about "gun violence" rather than simply pointing out to your friend that "guns are not the problem here. The issue is how to secure the schools, and guns are only a small part of the problem. Let's discuss what really matters."
